Taking on ass sweat

I get streaks, I have become used to puddles of piss, I dislike little hairs but there are not many things that disgust but like walking into a men's room to see the seat covered in ass sweat.
I know taking a shit is a big effort for some but how much pushing are you doing when you are precipitating from your ass?
Now I have a buddy who once literally detached his retina while taking an especially big dump so I guess how I can see this being almost a full contact sport for some of my larger friends but would it kill them to at least wipe down the seat afterwards??
